The intestinal floras of seven deep-sea fish retrieved at depths of from 3,200 to 5,900 m were examined for population sizes and growth responses to pressure. Large populations of culturable bacteria, ranging from 1.1 x 10(sup6) to 3.6 x 10(sup8) cells per ml of contents, were detected when samples were incubated at conditions characteristic of those of the deep sea. Culturable cell counts at in situ pressures were greater than those at atmospheric pressure in all samples. Most of the strains isolated by the spread-plating method at atmospheric pressure later proved barophilic. Barophilic bacteria were the predominant inhabitants of the abyssal fish intestines.
对从 3200 至 5900 米深处采集的七种深海鱼的肠道菌群进行了种群数量和对压力生长反应的研究。当样品在深海条件下培养时,检测到大量可培养细菌,其数量范围从每毫升内容物 1.1x10(sup6)到 3.6x10(sup8)个细胞。在所有样品中,原位压力下的可培养细胞计数均大于常压下的计数。在常压下用平板划线法分离的大多数菌株后来被证明是嗜压的。嗜压细菌是深渊鱼类肠道的主要栖息者。
